Is there an option, like on lights sources, to tell the object that has an emission shader to not cast shadows in the scene?
Add a transparency Node to a mix shader.
I have the following nodes:
Geometry, Emission, Transparent BSDF, Mix Shader, and Material Output.
The Geometry node makes the emitter one sided by connecting "Backface to Mix Shader/ Fac" (the grey input).
Transparent and Emissions also input the the Mix Shader/ (shader inputs the green ones)
Then the shader connects to the Material output.
